ל Lamed, the 12th letter, Gematria value 30

ל is pronounced similar to English L at the beginning of words or like L in Romance languages.  This is one of the easy letters for an European or English language speaker.  Pronunciation is the same in both Modern Hebrew and Aramaic.

כ \ ך Kaf - the 11th letter - gematria value 20

כ is the first letter, out of a set of 5 that has 2 forms. The regular form כ, when not at the end of the word, and the form ך when at the end of the word.

כ is also one of the BegadKephat letters that has a secondary pronunciation. כ is pronounced as K in both Modern Hebrew and Aramaic. The secondary pronunciation in both Hebrew and Aramaic is like that of ח (Khet) in Modern Hebrew. See https://unifyd.tv/community/posts/khet-numeric-value-8-is-the-firs

י Yod - numeric value 10

See how small that letter is? Jesus says: "For truly, I say to you, until heaven and earth pass away, not an iota (Yod), not a dot, will pass from the Law (Torah) until all is accomplished."

י is pronounced as Y in English, in both Modern Hebrew and Aramaic.

ט‎ Tet - numeric value 9

In Modern Hebrew ט‎ is pronounced as T in English (less breathy though) or like T in Romance languages. In Aramaic ט‎ is pronounced similar to T but more in the center of your mouth, with the tongue forming like a cup against the edges of the roof of the mouth.

Modern Hebrew does not make a difference between ט‎ (Tet) and ת (Tau) the last letter of the Hebrew/Aramaic alefbet (alphabet).

In Aramaic ט‎ (Tet) and ת (Tau) represent 2 different sounds, although sounding so similar, that an untrained ear might not capture the difference.

ח khet - numeric value 8

ח is the first consonant that does not have an equivalent pronunciation in English. In Modern Hebrew, it is pronounced exactly the same as secondary pronunciation of Kaf (כ). In Aramaic ח is pronounced like a harsher H, something between H and the Modern Hebrew pronunciation of ח. Many languages have both the sound of ה (He) and Aramaic sound of ח (Khet) marked as the same letter H. They don't capture the slight sound difference between the two, by using a different letter, like Hebrew/Aramaic does.

Modern pronunciation of ח is very noticeable, as if somebody is clearing up their throat of phlegm. Such sound is found also in languages like Dutch or German. For example, in German the CH in Bach or Dach is pronounced as  ח in Modern Hebrew.

חי (Khai) in Hebrew means life. Eve in Hebrew is חוה (Khava). אחי (Akhi) in both Hebrew and Aramaic means My Brother.
